Iterative systems in sold structures and filigree structures / study in structural surface strategy

The relationship between the structure and the shape in contemporary architecture has different formatsaccording to design and structural requirements. The integration is important formulas among these relationship, asthey form one unit in architecture, where the integration is characteristic by the important property which is theiterative system. One of the strategies to find iterative systems in contemporary architecture over traditional is calledstructural surface. Previous knowledge has been differed in explaining the functional of systems and it’smechanisms, especially in the relationship among the form and structure, so the problem has surfaced “the necessityto know the difference of the properties and types of iterative systems among solid and perforated structures withinthe structural surface strategy, and it’s role between the form and the structure”. to achieve the research’s goal “whatare the repetition and iterative systems in contemporary architectural structure and it’s role to determine the shape ofthe relationship among the structure and the form for building of different heights “, which has depended ondescriptive analytical method in three stage after defining the repetition in general, iterative system in particular andprevious knowledge criticism. First stage has focused on building a theoretical framework (characteristics and typesof the iterative systems in contemporary architectural structure and structural surface strategy). Second stage hasfocused on knowing the levels of the relationship among the form and the structure, By studying selected sampleswithin building of different height In addition to determine the important basic assumption of the research ,which is(iterative systems is differ in architectural structure (solid and perforated) , through characteristics of the iterativesystems with the system and the relationship of the surrounding environment according to it’s height (high ,medium)and it’s formation method (orthogonal ,free) ) . Third stage has focused on analyzing the results and conclusions as inthe role of the iterative systems (structural surface strategy) in producing the solid structures by adopting therepetition of the structural elements and generative rules in perforated structures, and use it to achieve a fusionamong the form and the structure to produce structures with efficiency and aesthetic appearance and structures thatreflect movement and dynamism. The level of this relationship are :( first: the compositionl, through theorganizational depth of the architectural structure. Second: the expressive, by finding three types of the relationshipare (the merging, the discrete, and the hybrid).
